Limit carbs, hit your macros, and stay in ketosis with the most complete keto tracker.
A keto diet works only when you stay under your daily carb threshold. MyNetDiary is the keto diet tracking app built for that level of precision — net carbs front and center, ketones logged alongside your meals, and a staff-verified database of 2 million+ foods tracking up to 108 nutrients. Free to start.
A keto or ketogenic diet limits carbs to roughly 20–50 grams per day, keeps protein moderate, and gets most calories from fat. The resulting ketosis state pushes the body to burn fat for energy, which typically aids weight loss faster than calorie-only diets. MyNetDiary makes the math invisible: log a meal, see your net carbs in real time, and know whether you have room left in your daily budget before you eat.
Highlights:
A good keto diet food tracking app does more than count calories. MyNetDiary covers every metric that actually moves the needle on a ketogenic plan, so you can see in one place whether your day added up the way you planned.
Fiber-adjusted net carbs for every food and meal, with a custom keto macros distribution you set once and adjust as you progress. Net carbs replace calories on the Dashboard, in meal totals, and in reports.
Log blood, urine, or breath ketone readings and chart trends over time. Track blood glucose, A1C, blood pressure, cholesterol, and medications alongside your food.
Weight trends, body measurements, and exercise live in the same diary as your food, so you can see how diet, activity, and ketones move together.
Keto has the narrowest margin for error of any popular diet. On a standard eating plan, accidentally overeating by 200 calories is a small blip. On keto, accidentally eating 15 extra grams of net carbs when your target is 25 can knock you out of ketosis entirely - and you may not realize it for days.
A solid keto diet food tracking app turns this precision problem into something manageable. Hidden carbs in sauces, dressings, and "sugar-free" products add up fast. In practice, people who track consistently stay within 5% of their carb target, while those who estimate are off by 30-50%. On most diets, that gap is annoying. On keto, it is the difference between the diet working and not working. Using an app for tracking keto diet takes the guesswork out of daily food decisions and lets you focus on actually enjoying what you eat.
Reports and charts help you see the big picture and adjust your Keto diet as needed.
MyNetDiary can track up to 107 nutrients, which is crucial for Keto diet. Limiting fruits and vegetables in your diet requires you to make sure you don't develop vitamin and mineral deficiencies.
For the Keto diet, MyNetDiary replaces calories with net carbs for all screens in the app. You'll see net carbs for foods, meal and day totals, as well as on the Dashboard.

A keto diet tracking app automates the precise carb counting that keto demands. It calculates net carbs automatically, monitors your macro ratios in real time, flags foods that might push you over your carb limit, and tracks ketone levels alongside your meals. Without a reliable app for keto diet tracking, most people consistently underestimate their carb intake by 30-50% - more than enough to prevent ketosis entirely.
Keto works by keeping your body in a metabolic state called ketosis, which requires strict carb limits (usually 20-50g of net carbs per day). Even small miscalculations - hidden carbs in sauces, dressings, or "sugar-free" products - can knock you out of ketosis. Consistent tracking is the only reliable way to know whether your daily food choices are actually keeping you in the zone.
Look for automatic net carb calculation (not just total carbs), a verified food database (crowdsourced databases have carb-count errors that can break ketosis), micronutrient tracking beyond basic macros, ketone and blood glucose logging, a keto food scoring system, and keto-specific recipes. Speed of food logging also matters - a clunky app discourages daily use.
Yes. MyNetDiary integrates with Apple Health, Google Health, Fitbit, Garmin, and Withings. Exercise data, step counts, and body metrics sync automatically. Many additional devices and apps are accessible through Apple Health and Google Health, so the keto diet tracker app works within your existing health ecosystem.
Losing 30 pounds in 3 months (roughly 2.5 pounds per week) is ambitious but possible for some people on keto, especially those starting at a higher weight. Initial weight loss on keto is often faster due to water loss as glycogen stores deplete. Long-term results depend on consistent carb restriction, adequate protein, caloric deficit, and individual metabolism. A keto diet tracker app helps you stay precise and accountable throughout the process. Always consult your healthcare provider before starting a new diet.
